### BARS::Gila Bend On Presidents Day 2006

This road sign is on AZ Hwy-238 just east of Gila Bend, Arizona.

The road sign says...

```   +---------------+
| Buckeye    32 |
| Jct I-10   34 |
| Phoenix    64 |
+---------------+
```
```   the numbers are:  10  32  34  64

the math is:  sqrt(64) + 34 - 32 =  10

observe...
sqrt(64) = 8

[solve for 'n']  sqrt(64) + n - 32 = 10

rs42Eval:  34 - 64 / 32 + 10 = 42
* the "Answer to Life, the Universe, and Everything"

more math:  sqrt(64) * (34 - 32) = 10base-16

[solve for '10base-16']

observe...
base-16 is called hexadecimal
hexadecimal digits are 0-9 and A-F (or a-f)
10 decimal is A (or a) is hexadecimal
```

A student in the Fall 2006 MAT102 class thought the `10` should be a `-10`.

```   sqrt(64) + 34 - 32 =  abs(-10)
```
##### Update::2009.02.20

This BARS was selected to be one of the BARS of the Week for week #6 of the spring 2009 semester.

```   the numbers are:  10  32  34  64

more math:  log(10) * (34 - 32) = cuberoot(sqrt(64))
....or....  log(10) * (34 - 32) = (64^(1/2))^(1/3)

more math:  defactorial(34 - 10) * sqrt(64) = 32

number system math:  10^(34 - 32) = 6416

[exercise]  Let I be Roman numeral one.  Find an equation(s)
using the numbers:  1  10  32  34  64
```

##### Update::2010.02.12

This BARS was selected to be one of the BARS of the Week for week #5 of the spring 2010 semester.

RoadHacker visited Gila Bend on 5 February 2010 and took another picture of this road sign.

```   the numbers are:  10  32  34  64

more math:  34 - 32 = sqrt(64 % 10)

rsStateEval:  34 + 32 - 10 - sqrt(64) = 48
* Arizona was the 48th state admitted to the Union.

rsStateEval:  (64 % 10)! * (34 - 32) = 48
* Arizona was the 48th state admitted to the Union.

rsAgeEval:  64 - 34 + 32 - 10 = 52
* MathBabbler was 52 years young when he found this equation
and RoadHacker was 52 years young when he got a new picture
of this road sign.

off-by-one rsHwyEval:  32 + 34 + sqrt(64) + 10 = 85-1
* This road sign is on northbound AZ Hwy-85.
